.eu stratum servers if your miners are located in Europe, Russia and other regions, near to Europe

.us stratum servers if your miners are located in USA, Australia and other regions, near to USA

You can fine determine best location by running simplepingutility from Windows Command Prompt or Linux Shell.

IMPORTANT!Youmustrun this from the location of your miners, ideally directly on your miners,NOTfrom your home PC/Desktop/Notebook (the only exception is when your miner or GPU is actually connected to your PC/Desktop/Notebook).

If you are using windows, run this command foreachpool stratum server location (if you do not have telnet installed seehere for install instructions):

ping -n 50 -l 128 SERVER

If you are using Linux, run this command foreach stratum server location:

ping -c 50 -s 128 SERVER

After all the tests are finished (50 pings for each location) you'll get results with Minimum = X ms, Maximum = Y ms, Average = Z ms latency (or min/avg/max/mdev = X/Y/Z/W ms). You're looking forAverage or avgnumber. Pick the location for which the test gives you theLOWESTAverage or avg number of ms.

It is also important that you receive0% packet lossin the ping results. If you get significant packet loss for a particular location it might be wiser to choose a location with slightly highermsresults, but with lower or zero packet loss.
